Process Research Ortech has been tasked with developing mineral processing and metallurgical process flow-sheets for the recovery of lithium from hard rock spodumene mineralisation.

The process will take around 16-22 weeks, and is a necessary step towards commercialisation of lithium extraction and purification from the spodumene through a planned pilot project, said United.

United Lithium signed a non-binding Letter of Intent with Leading Edge Materials covering the 100% acquisition of the Bergby Lithium project last December.

The Bergby lithium project, located in central Sweden 25km north of Gavle, was staked by Leading Edge in 2016. It covers three exploration permits for a total of 1903Ha.

A prospecting campaign with mapping and sampling identified an extensive lithium-mineralized spodumene pegmatite boulder field and outcrops.
